Essay on Global Positioning Systems

The difficulty comes in the very word measurement which implies some form of numerical logic. If we look at known distance measurements one

But I did noticed that snice we did not go too far the GPS did not register that we were moving and when we went inside the Academic building the GPS device completely fail and I assume that it was because we were standing underneath a big metal object that was deflecting the GPS signal. Also when it came to direction it was hard to interpret what was north on the GPS screen, so it did not help when we try to find where north

Lots of people around the world use GPS on their phones and in their cars. Before the Space Race and GPS’s, it would take people much longer to get to their

The development of the Global Positioning System, GPS for short, was accelerated by Sputnik in more than one way. When Sputnik launched, Guier and Wieffenback were able to measure the doppler shift in the signal that was broadcast from Sputnik and successfully estimate the location of Sputnik. After telling their Laboratory’s Director about their discovery they were granted

A parallax is used to measure a star’s distance. During every 6 months’ astronomers look at a star and record it they then measure the distance it moved to find the actual distance from the sun.

3. What is a distance determination? How is this done? A distance determination is the process of estimating the distance between where a shot is fired and its target. This is often done by looking at the patterns of powder residue and the shot pattern.

Since the advent of humanity, nature has always proved to provide us with sustenance and opportunities for adventure. Yet, it was not only the lack of funds for urban adventure that drew millions of millennials into the woods. In May of 2000, GPS had a revolutionary improvement. This advancement of the global positioning system allowed users to engage and control selective availability, enabling them to pinpoint their exact location and other select locations. The White House stated that, anyone could use GPS to isolate, "the location of items left behind for later recovery.” Thus, sparking the origin of

Air travel has been massively impacted by GPS. Flights are currently tracked by radar18 which mostly works well over well-populated areas but can be problematic over remote, mountainous areas where there are less radar stations or over the ocean. Planes must stick to established routes in these areas and remain more

Today, we can send information all over the world instantly; however movement and activities can be tracked through computers and cell phones. With new and improved technology, it can improve lives, increase public safety, build wealth and promote efficiencies in how we use scarce resources. Researchers,

Primary Calibrators were set up to bounce radar waves throughout the solar system to help determine distances between objects and Earth. Secondary Calibrators were designed to determine brightness of stars from Earth. The method of brightness

LORAN is a pulsed hyperbolic system. Which means that hyperbolic lines of position are determined by noting differences in time of reception of synchronized pulses from widely spaced transmitting stations, primary and secondary, A primary station broadcasts an uninterrupted series of pulses of fixed duration and at a fixed rate. A secondary station, 200–300 miles away, automatically transmits its own signals, maintaining a frequency and pulse duration in accord with those of the primary station. The secondary station maintains a fixed time difference between its reception of the primary signal pulse and the sending out of its own. The identified time difference of arrival of the two pulses locates the craft some where on a curve and every point of which is located at a constant difference in distance between the stations.

The U.S. Department of Defense began developing the Global Positioning System (GPS) in the mid-1970s, eventually spending

There are 24 satellites that circle the earth every 12 hours. These satellites are split into six groups of four and each group creates an orbital plane. These six orbital planes allow the satellites to move in a way that covers the earth completely. GPS satellites transmit signals to equipment on the ground. An example is a GPS receiver (GPS receiver can only receive the signals form the satellites but they can’t transmit any signals). The receivers work best in an open outdoor area where there is a clear view to the sky. At any time there are always four visible satellites. The GPS receiver can calculate how far each satellite is based on the time it took the signal to reach the receiver. Using the distance from each satellite that the receiver calculated it could then use a process called trilateration to pinpoint the location of the receiver [1].

GPS has made our lives so much easier. We don't have to print out directions before heading to an unknown address. GPS-enabled devices we carry with us daily allows us to travel freely without worrying about getting lost. There are also a number of GPS devices to help us keep track of our children. It's a dangerous world out there, and at any moment, we might need to know where our children are located.

[CE 1.1] This is a career episode which details my experiences and knowledge gained while working on developing a GPS enabled device for a recreational sport called Geocaching as part of my unit of study Embedded system design during my final semester. I worked on this project along with my team mates with whom I shared common interests in the field of my desire. I was guided by my lecturer Dr. Jason White during the whole period of this particular development.
